To provide a process, whereby a low molecular weight organic compound having at most 20 carbon atoms present in a trace amount in a cloth made of chemical fibers treated with a water and oil repellent agent, can be accurately analyzed. A process for analyzing a low molecular weight organic compound having at most 20 carbon atoms in a cloth made of chemical fibers treated with a water and oil repellent agent, which comprises (a) a step of dissolving the cloth made of chemical fibers treat-ed with a water and oil repellent agent in a solvent capable of dissolving a resin constituting the cloth, to obtain a solution, (b) a step of mixing the solution with a solvent capable of agglomerating the resin to agglomerate the resin, to obtain a liquid contain-ing a resin agglomerate, (c) a step of subjecting the liquid containing a resin agglomerate to solid-liquid separation to obtain a liq-uid phase, and (d) a step of measuring the concentration of a low molecular weight compound having at most 20 carbon atoms in the liquid phase by means of a liquid chromatograph-mass spectrometer, a liquid chromatograph-tandem mass spectrometer, a gas chromatograph-mass spectrometer or a gas chromatograph-tandem mass spectrometer.
